a) The pertinent investigations should be carried out taking into consideration the relationship between the different facts of the case and the context in which they occurred, avoiding omissions in gathering evidence and following logical lines of inquiry; b) The investigations should seek to effectively identify and individualize those responsible for the violations committed; c) Due diligence in the investigation implies that all competent State authorities are required to collaborate in gathering evidence and to refrain from actions that imply the obstruction of the investigative process; d) The competent authorities must carry out the relevant investigations ex officio and to that end must have access to all the logistical and scientific resources necessary to collect and process the evidence; likewise, those who participate in the investigation, including the victims’ families, the witnesses, and the officials of the justice system, must have due guarantees of safety. 249. The Court considers, as it has established in its constant case law287, that the State must guarantee victim’s family members full access and the ability to act in all the stages of the investigation and prosecution of those responsible, according to domestic law and the provisions of the American Convention. Moreover, the results of the proceedings must be publicly disclosed with the aim of informing Venezuelan society of the truth of the facts of this case, and those responsible for them. 250. Finally, as on other occasions,288 the Court orders the State to examine, in accordance with the relevant disciplinary provisions, any potential procedural and investigative irregularities related to this case and, if applicable, to sanction the conduct of the relevant public servants. C. - Measures of rehabilitation, satisfaction and guarantees of nonrepetition 251. As established in its case law289 and considering that the Judgment constitutes per se a form of reparation, the Court deems it appropriate to establish the following measures of reparation. C.1. Rehabilitation Measures 252. The representatives requested that the Court order the State “to guarantee that the victims receive the medical and psychological treatment they need, from competent professionals, including the supply of any medications required.” Additionally, they requested that the State cover “other expenses generated alongside the provision of treatment, such as transportation costs, among other needs that may arise.” 253. In accordance with the preceding paragraphs and as it has done in other cases,290 the Court orders the State to immediately, adequately and effectively provide medical and psychological care to the victims who request it, as follows: 287 Cf.
